The use of water transport is limited by all the following except
Answer Details
The use of water transport is limited by various factors, including the width of valleys, presence of waterfalls, floating vegetation, seasonality, and narrow gorges. However, the question asks us to identify the exception among these factors, which means we need to find the factor that does not limit the use of water transport.
The answer is "wide valleys." Wide valleys actually facilitate the use of water transport because they provide ample space for boats and ships to navigate. In fact, many major rivers around the world, such as the Amazon, Nile, and Mississippi, have wide valleys that have been used for transportation for centuries.
On the other hand, waterfalls, floating vegetation, seasonality, and narrow gorges can all make water transport difficult or impossible. Waterfalls and rapids can be dangerous and require portages or other means of bypassing them. Floating vegetation can clog waterways and impede navigation. Seasonality, such as changes in water levels due to drought or flood, can affect the ability of boats to travel. Narrow gorges can make navigation difficult or impossible due to the presence of rocks and other obstacles.
